| gallium | <chemistry, element> A rare metallic element, found in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarcable for its low melting point (86 F, 30C). The element was predicted with most of its properties, under the name ekaluminium, by the Russian chemist Mendelejeff, on the basis of the Periodic law. This prediction was verified in its discovery by the French chemist Lecoq de Boisbaudran by its characteristic spectrum (two violet lines), in an examination of a zinc blende from the Pyrenees. Atomic weight: 69.9 Abbreviation: Ga Origin: NL, fr. L. Gallia France. Source: Websters Dictionary (01 Mar 1998) |

| gallium |
CAS Number: 7440-55-3. Gallium is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures, which makes possible its use in high-temperature thermometers. Ultra-pure gallium has a beautiful, silvery appearance. Gallium compounds are also used to create semiconductors and microwave equipment. Chemical formula = Ga. Molecular weight = 69.72 g/mol.

| gallium |
Gallium is not produced in the United States, and demand is satisfied by imports, primarily high-purity material from France and low-purity material from Kazakhstan and Russia. More than 95% of gallium consumed in the United States is in the form of gallium arsenide (GaAs). Analog integrated circuits are the largest application for gallium, with optoelectronic devices [mostly laser diodes and light-emitting diodes] as the second largest end use.
